We enjoy photographing architecture wherever we go. Since when did it become against the law? What's going on here?

Photographer Carols Miller and his friend were passing time while waiting for a Metrorail by taking photos of the Dade County Courthouse, which was built during the Roaring 20s and is considered to be a stunning piece of architecture.
"Then considered one of the more monumental structures in Florida, Dade County's 27-story Neoclassical-style courthouse was begun in 1925," says this historical account of the structure.
Suddenly, a voice blared over a loudspeaker ordering them to cease and desist with the photographs. The pair ignored the order, but shortly thereafter a 50 State security guard came onto the platform and confronted them.
Miller sensed that his civil rights were about to be violated once more, he asked his companion to begin videotaping the exchange. Here's the video
